Fin'. S is a detail at reduced size of some of the parts shown in Fig. 2.

In F' s 'l and 5. the parts are shown in on in tull lines, and in their alposition in dotted lines. Yts ci' the machine herein, involved )ally bctw In th andards 1() 'orner'. The main shaft of own. at 12, and the present itself` with the driving and settinfr of that shaft` upon the standards 1() and 11 is a piece of insulation 13. and secured to the onder 1 oiI this a in griet 14, Pivoted on a i in the lonel part of the apparat1 channel and` secured in this cha. i bracket 17. Mounted upon the bracl is another iet 18, the pole 1Q ol which is closely adjacent to the pole 2() et magnet 141. Electrical connections for the magnets are shown at 21 and i The parte are so arranged that when an electrical im se is sent vthru the two mag nets, the? attract each other, and the lower rn i with its supporting` parts is inoved the pivot 15 from the full line t0 the dotted line position shown in Fig. 2. lVhen the circuit is broken tiru the inagnets. the moved parts fall back by gravity to their normal position.

An extended part of the channel 16 is in the forni of an arm 23 havingr its upper end 24 bent over in a convenient form to strike 1921. Seria] No. 457,762.

the teeth of a star wheel 25 fast on shaft 12. Pii'oted to the channel 16 at 26 is another arm 27 which has its upper end 28 simiiarlybent over to strike the teeth oi the star wheel 25. A spring` 50 holds arm 2T against a projection 51 on arm 23, so that normally arnis 23 and 2T act as if they were rigidly secured together. In addition to the gravity action before mentioned as acting on the magnet 1S and channel 16, there is a spring 29 connected to arm 23 and acting to pull said arm and associated parts downward. This normally keeps the end 28 of arin 27 in engagement with a tooth of the star wheel, and end 24 of arin 23 out ot' such engagement,

Pivoted at 30 on the irame is a pawl 3l which normally rests on the tip of one tooth of the Star wheel. At 32 on opposite sides of the pawl arm are pins secured in the frame of the apparatus. These pins are for the purpose. oit limiting the movement of the pawl 31 to as short a throw as will serve the purpose. lVhen the star wheel is advanced in a contra-clockwise direction, as shown in Fig. 2, a tooth slips from under the pawl. and said pawl drops to rest on the lower pin This is not a drop to the full depth ot the tooth. but only enough to prevent a reverse movement ot the wheel 25, In the standing' position shown in Fig. 2, the end of the star wheel tooth which is under the pawl is very close to the end of the pawl so that a very short advance of the wheel permits the pawl to drop into its lower position.

The circuit 'for the magnets 14 and is connected to a master clock or to some other means by which said circuit is closed once each minute and immediately thereafter is broken. lVhen the circuit is closed. the magnet 18 is raised as before ilescr1loed. and

this causes the end 241- of arm 2.27 to strike one tooth of. the wheel 25 and come to rest in the crotch between two teeth. This ad- Ycanoes the wheel a small part oif the distance between one tooth and the next, which advance is suiiicient to permit the pawl 31 to drop behind the tooth on which it was previously supported.

When the circuit is broken thru the inagnets, the arm 23 drops and causes the end 28 of arm 27 to strike a tooth which was advanced into its path by the previous action of arin This advances the star wheel the remainder7 and main part, of the .arm which f normally holds distance bete-.Teen `one tooth and-the next. T he `lower and normal position oit 'the anagnet 18 is determined by the end Q8 comingto rest in the crotch between two teeth on the star Wheel. When another impnlse flows thru the magnets, the ratchet Wheel will be advanced another step, and so on.

On the end of shaft 1Q is a'bevel gear 33 which engages another bevel gear 34 on shatt. nected thru a train et gearing 36 with a clock hand 37 which moves over `a clock dial 153". The hand 37 is theffminute hand ot the clock and aadvances .one step each time that the magnet liSimoves to its attr cted position.

Pivoted at 39 on thefjtrame Worin of' the machine is a lever which has arms 46,41, 42, 4:3 and dll. rThe arm is a weighted l J4he yilever with arm 2in Contact with a sha't it?) which i art othevmachine but which only stop as tai-'as present matters are concerned. The :arm t1 has thereon a linger piece el-G by which the lever may `be manually moved toai'iextent which will brin g arm f1-1 against stop Whenso movedV the curved Aiiiace di' on ythe lower end ot arm t3 passes over the end 2a ot ;arm 2B andlholds such `arm trom being moved to engagement with the teeth of `star Wheel 25. 4immediately yzitter the curved tace it-7 first pe `'ses over endQl7 the armzllelstrikes the end 28 oit mm2? to more saidarm on its pivotdagainst `the-,tension of spring' 50 until the end 28 is entirely clear oi the teeth of star `wheel ln this condition thel clock may be setfby manually moving the'hand 37 iforward` which. is the direction on the star Wheel `which the-pareil 31 permits it to more.

The operations just described serre toset the clock mechanism, and consequently the shaft 12 which is connected thereto by s ring.
